PATENT OFFICE ASSIGNOB '1'0 AUTOPOINT COMPANY, OF

1 CHICAGO, IIlLmOIS, A CORPOBATION OF ILLINOIS PENCIL Application flled April 1,

My invention relates to a head and a ring holder for cylindrical objects, and particularly pencilsgof the mechanical or other types.

An obj'ct of my iiivention is to provide a device adapted for use with pencils of the mechancal type which shall be more particularly useful in connection with the common automatic, telephone. It is well known that in the operation of the automatic telephone' instruments, the finger is necessary to properly revolve the dial to secure a connection; In many cases, where one is constantly using an instrument of this character, the fingers are apt to become more or less sore, because of the continued strain on the tips thereof, as well as to become soiled by contact with the dial The device of my invention is intended to eliminate all the objections attendant upon the operation of such a telephone, in that the head of the pencil is readily placed in the aperture provided, and when the dal is turned the head will revolve accordingly, th pencil barrel remaining stationary. f

Another object of my invention is to provide a ring holder for use in connection with a device of this character. It is evident that a greater part of the value of a device of this character is the fact that to serve 'its pur-' pose, it must necessarily be kept close to the 3o instrument. The vring holder contemplated by my invention is adapted to be made as a part of the device, and to be attached to a cord or spring near the telephone so that the device will be always ready to serve its function. A further object in the ring holder here disclosed is in the simple feature of locking the device so that it cannot become loose or separated from the barrel of the encil.

The invention will be more rea 'ly understood by reference to the accompanying drawing, in which:

Fig. 1 is a side elevation partly broken in section showing a device constructed in accordance with my invention;

Fig. 2 is a plan view thereof; v l Fig. 3 is a detail view and side elevation of 4 the ring holder; 4 v

Fig. 4 is a cross section of the ring holder 5o and washer, taken on the line 4-4'of Fig. 3;

1927. serial no. 180,198.

Fig. 5 is a detail view of the tube fastened to the head; and

Fig. 6 is a plan view of the ring washer.

By reference to the drawing, it will be seen that my invention consists of a substantially cylindrical body, 10, having at one end thereof a tip, 11, and at the other end'a head, 12. The head may be of substantially bulbous or spherical contour, having a shank, 13, on one side thereof, with an aperture therein to receive the open ended tube 14, which is permanently fastened at one end to the head. The lower end of the tube, 14 is flared as at 15, indicated in Fig. 5, for the purpose of retaining'a sleeve 16 which fits over the tube 14 and 'extends from the flared portion to the vbase or shank 13 of the head 12. Thus the head and tube are permitted free rotary movement and may revolve within the sleeve. The sleeve 16 is adapted to be received within an axial bore, 17, in the tubular body, and be frictionally held therein. i The interior of the tube 14 may be used as a depository for spare leads if the 'device is used on a pencil.

Located at any convenent point alon the side of the cylindrical body is the ring ho der. The ring holder consists of an eye, 18, having a screw threaded ortion, 19, adapted to be received within a threaded aperture, 20 in the barrel, 10. A ring, 21, engages the eye as indicated in Fig. v3. Disposed between the eye and the barrel is a washer 22 of conventional Shape, having an -aperture substantially the diameter of the threaded portion 194of the eye. Oppositely disposed notches, 23, are formed inv the metal surrounding the hole, said notches serving to receive the sides of the lower curvature of the eye, 18,-for a purpose hereafter to be described.

It is evident that by providing the notches, 23, in the washer, 22, the eye may be screwed down lower than the top lof the washer be- V cause the lower curvature of the eye is received within the-'notches and the washer revolves with the eye until the eye is screwed down tight. Thus by bending down the opposite sides of the'washer after screwing down the eye, the eye becomes locked and prevented from unscrewing.

J 'Thus it will be4 seen that I have provided a 10o ali device vvhich consists of a substantially cylindrical body having a cylindrical body v provided with a removable head and a locked eye or ring holder. It Will be evident that the head need not be strictly spherical, but may be of any size or shape convenient for the purpose described. Likewise the outside periphery of the washer need not necessarily be of circular form, but may function as Well if irre lar. F urther, instead of providing note es in the inside periphery of the washer, projections may be punched upward to contact the sides of the lovver curvature of the eye, and serve equally Well to prevent unscrewin of the eye.

As a ove pointed out, modifications an variations of the construction described may be made Within the skill of the mechanic and I do not wish to be limited except as indicated in the appended claims.

I claim:

1. In a device of the class described, a substantially cylindrical body having an axial bore, a spherical portion at one end thereof constitutlng a head, a tube permanently secured to said head at one end thereof, and

flared at its opposite end, a sleeve substantially the 'Iength of said tube adapted to fit over said tube and to be received within and frictionally engage the Walls of the'V bore of said cylindrical body, to adapt the head to rotate freely on said tube within the bore.

2.' In eombination, a rod-like body having an axial bore, a spherical head, a hollow cylinder permanently united to said head, a sleeve surrounding said cylinder and freely rotatable thereon and held against longitudinal separation therefrom, said sleeve being adapted to -be frictionally held in said bore and to perlnit said head to rotate f-reely.

3. In combination, a rodlike body having an axial bore, a spherical head, a hollow cylinder telescopically engaging said body and said head, a sleeve surrounding-said cylinder and freely rotatable relative thereto and held against longitudinal separationf therefrom, said sleeve being adapted to be frietionally lheld in said bore and to permit said head and cylinder to rotate freely.

4. In combination, a body having an axial bore, a spherical head, a cylindrical part held in fixed position, a rotatable part 'held in fixed relation to said cylinder part, said rotatable part being connected to said spherical ead.

In testimony whereof I have aflixed my signature.
